All the necessary information for foreign students about academic
programs, recruitment and procedures can be found at: http://www.dfait-maeci.gc.ca/ics-cki/recruit-interstudent-e.asp,
but here is a bit of information.
You will need to have a proficient level of understanding
of either French or English, to be able to follow course
lectures and reading assignments. Language requirements
are set by each institution. Some post-secondary institutions
might ask you to take a language test such as TOEFL or IELTS,
but Canadian universities often have their own tests for
students. They may charge a fee for the tests, which you
will have to pay yourself. Your local Canadian Education
Center (CEC) or the admissions staff at the universities,
can provide information on English examination tests acceptable
to Canadian universities. CEC staff can also advise students
on whether they may be exempted from taking an English examination.
On the other hand if you are interested in studying at a
French language institution, there are no standardized French
language tests that international students are required
to pass in order to qualify for a admission. French-Canadian
universities, however, will determine the level of a student's
French language skills on a case-by-case basis, and may
choose to administer their own written tests if language
skills are in question.
There is no national Canadian entrance exam. The only exam
requirement for admissions is an English language exam for
those whose mother tongue is not English.
